Description

Technical Field

[0001] This application relates to the field of electricity metering box technology, and in particular to an outdoor waterproof electricity metering box. Background Technology

[0002] An electricity metering box, also known as a power metering box, is a closed, specialized enclosure primarily used to install and protect metering equipment such as electricity meters, transformers, terminals, and data collectors. It is widely used in power systems ranging from 0.4kV low voltage to 35kV medium voltage, providing a physical carrier and security protection for electricity metering for various power users. The electricity metering box is a closed enclosure in a power system used for installing, protecting, and managing electricity metering devices. Its core functions are to accurately measure electricity consumption, ensure metering security and prevent electricity theft, protect equipment from environmental isolation, and support electricity billing and power consumption monitoring. It is a fundamental piece of equipment for electricity billing and power grid operation and maintenance.

[0003] In existing electricity metering boxes, the internal components continuously generate heat during operation. If this heat is not dissipated in time and accumulates excessively, it will directly reduce the efficiency of the components and even cause performance degradation, affecting the stable operation and metering accuracy of the metering device. Therefore, existing metering boxes are generally equipped with heat dissipation devices, with the mainstream solution being ventilation and heat dissipation achieved by opening heat dissipation holes.

[0004] Its working logic is to use the air circulation channel formed by the heat dissipation holes to expel the hot air accumulated inside the box, while guiding the outside cold air into the box. Through the convection exchange of hot and cold air inside and outside the box, cooling and heat dissipation are achieved to ensure the normal operation of the metering device. However, this heat dissipation solution has obvious protection defects in practical applications, especially in humid environments and rainy days, which can easily cause safety hazards.

[0005] During rainy weather, rainwater can directly splash into the metering box through the ventilation holes. Even on non-rainy days, if the outside air humidity is high, moisture can also seep into the box through the ventilation holes, failing to provide effective protection. The electricity meter, wiring terminals, and other components inside the metering box are precision electrical components with extremely high requirements for insulation. Moisture or rainwater intrusion can damage the insulation performance of these components, easily causing short circuits in the internal wiring. This can not only lead to metering device malfunctions and shutdowns, and distorted metering data, but may also burn out components and even cause serious safety accidents such as fires, threatening the safe operation of the power distribution network and the safety of the surrounding environment.

[0006] Therefore, it is necessary to propose an outdoor waterproof power metering box to solve the above problems. Utility Model Content

[0007] This application provides an outdoor waterproof electricity metering box. In order to improve the technical problems in the related technology that the metering device generates heat during operation, existing metering boxes mostly use heat dissipation holes for ventilation and heat dissipation. However, in humid environments or rainy days, rainwater can easily splash in and water vapor can easily penetrate. After entering the box, it can damage the insulation of electrical components, which can easily cause short circuits, resulting in metering failure, component damage, and affecting operational safety and metering accuracy.

[0008] This application provides an outdoor waterproof electricity metering box, including a box body and a door on the box body. The side wall of the box body is provided with an array of first heat dissipation holes near the lower end. The box body is provided with partitions at both ends to isolate electrical components. The partitions are provided with an array of second heat dissipation holes near the upper end to prevent rainwater from splashing into the components through the first heat dissipation holes. A baffle assembly is provided on the outer side wall of the housing at the position corresponding to the first heat dissipation hole. The baffle assembly includes a fixing frame and a lifting plate that is telescopically installed in the fixing frame, which can reduce the exposed area of ​​the first heat dissipation hole and reduce water mist intrusion.

[0009] The technical solutions described above in this application embodiment have at least the following technical effects: through the coordinated design of graded heat dissipation holes, isolation structure and adjustable baffle, while ensuring effective convection heat dissipation inside the box, it can effectively block rainwater splashing in, reduce water mist intrusion, avoid damage to electrical components due to moisture, significantly improve waterproof performance and operational reliability, and is suitable for complex outdoor environments such as humid and rainy days.

[0010] In this embodiment, the lifting plate blocks the first heat dissipation hole from top to bottom.

[0011] This technical solution reduces the size of the first heat dissipation hole, effectively preventing rainwater from splashing in and reducing water mist intrusion, thus avoiding damage to electrical components due to moisture. It significantly improves waterproof performance and operational reliability, making it suitable for complex outdoor environments such as humid and rainy days, while also reducing the overlap area between the first and second heat dissipation holes.

[0012] In this embodiment, the box body and the partition are welded together to prevent rainwater from leaking through the connection between the partition and the box body.

[0013] This technical solution involves welding the box body and partitions together to eliminate the risk of leakage at the joints. Combined with the overall waterproof and heat dissipation structure, it significantly improves the sealing and waterproof performance of the metering box, ensures the safe operation of electrical components, and is suitable for complex outdoor environments.

[0014] In this embodiment, the second heat dissipation hole overlaps with the entire first heat dissipation hole.

[0015] This technical solution facilitates heat dissipation from the inside of the device when the baffle assembly is fully open, and reduces rainwater inflow into the device when the baffle assembly partially blocks the first heat dissipation hole.

[0016] In this embodiment, the partition and the cavity of the side wall of the box form an isolation cavity. An inclined plate is provided on the bottom of the isolation cavity. A drainage hole is provided on the rear wall of the box at the lower end of the inclined plate to facilitate the discharge of rainwater splashed in from the first heat dissipation hole.

[0017] This technical solution enables rainwater to be discharged in a directional manner through the isolation chamber, inclined plate and drainage hole, preventing rainwater from accumulating. Together with the overall waterproof and heat dissipation structure, it significantly improves the metering box's anti-leakage capability, ensures the safe operation of components, and is suitable for complex outdoor environments.

[0018] In this embodiment, a guide groove is provided in the fixed frame, and the lifting plate moves up and down through the guide groove. A spring pin is provided on the side wall of the lifting plate. Multiple limiting grooves are arrayed in the guide groove of the fixed frame at positions corresponding to the spring pins to facilitate the fixed positioning of the lifting plate.

[0019] This technical solution achieves smooth adjustment and reliable positioning of the lifting plate through the coordinated action of the guide groove, spring pin, and limit groove. It can flexibly adapt to different environments by adjusting the area of ​​the heat dissipation holes, and the overall structure enhances waterproof and heat dissipation adaptability, ensuring stable operation of the metering box.

[0020] In this embodiment, the lifting plate is also provided with a triangular handrail to facilitate the user to lift the lifting plate, and the top of the lifting plate is also provided with a water-blocking strip that abuts against the side wall of the box.

[0021] This technical solution allows for convenient adjustment of the lifting plate via a triangular handrail, while the water-blocking strip enhances sealing and waterproofing. Together with the overall structure, it improves ease of operation and waterproofing performance, ensuring stable operation of the metering box and adapting to complex outdoor environments.

[0022] In this embodiment, the box body is also provided with an inclined rain shield.

[0023] This technical solution uses a tilted rain shield in front of the enclosure to block rain, which, together with the overall waterproof and heat dissipation structure, reduces the risk of rainwater intrusion and improves outdoor operational stability and waterproof reliability.

[0024] Beneficial effects: This patented waterproof energy metering box effectively solves the core pain point of the conflict between heat dissipation and waterproofing in existing metering boxes through a multi-structure collaborative design, resulting in significant overall benefits, as detailed below: Firstly, a multi-layered, three-dimensional waterproof system is constructed to comprehensively block the intrusion of rainwater and moisture. An inclined rain shield at the front prevents rainwater from washing over the enclosure and the first ventilation hole, reducing the risk of intrusion at the source. The baffle assembly adjusts the exposed area of ​​the ventilation holes via a retractable lifting plate; in humid or rainy weather, the hole diameter is reduced to minimize water mist intrusion. Combined with the water-blocking strip on top of the lifting plate, which abuts against the side wall of the enclosure, gaps are filled to prevent leakage. The enclosure and partitions are welded together to eliminate connection gaps and prevent weak points from leaking. The isolation chamber physically isolates rainwater from electrical components, and with the inclined plate's directional flow guide and drainage holes for rapid drainage, a waterproof closed loop of blocking, isolating, guiding, and draining is formed, completely solving the problems of rainwater splashing and moisture penetration.

[0025] Secondly, while ensuring efficient heat dissipation, a precise balance between waterproofing and heat dissipation is achieved. The first heat dissipation hole is positioned at a low position, while the second heat dissipation hole is positioned at a high position and is also higher overall, forming a convection channel with a height difference between the top and bottom, which promotes the natural rise and exhaust of hot air inside the box, thereby improving heat dissipation efficiency. None of the waterproof structures block the heat dissipation channels, and the adjustable design of the baffle assembly can dynamically adapt to the heat dissipation needs according to the environment, avoiding the problem of insufficient heat dissipation caused by a single waterproof structure.

[0026] Third, it improves structural reliability and ease of use. The welded box and partition are firmly connected and adaptable to the vibration and impact of complex outdoor environments. The lifting plate moves precisely through the guide groove, and the spring pin and limit groove work together to achieve reliable multi-level limit. With the triangular handrail, the adjustment operation is effortless and convenient. The whole structure design does not rely on electronic components, so it has strong stability and low maintenance cost.

[0027] In summary, this patent significantly improves waterproof sealing performance while ensuring effective heat dissipation of the metering box, avoiding damage to electrical components due to moisture, reducing the risk of short circuits and metering failures, greatly improving operational reliability and service life, and can stably adapt to complex outdoor environments such as humid and rainy days, possessing strong practical value and promotion prospects.

[0029] In existing electricity metering boxes, the internal components continuously generate heat during operation. If this heat is not dissipated in time and accumulates excessively, it will directly reduce the efficiency of the components and even cause performance degradation, affecting the stable operation and metering accuracy of the metering device. Therefore, existing metering boxes are generally equipped with heat dissipation devices, with the mainstream solution being ventilation and heat dissipation achieved by opening heat dissipation holes.

[0030] Its working logic is to use the air circulation channel formed by the heat dissipation holes to expel the hot air accumulated inside the box, while guiding the outside cold air into the box. Through the convection exchange of hot and cold air inside and outside the box, cooling and heat dissipation are achieved to ensure the normal operation of the metering device. However, this heat dissipation solution has obvious protection defects in practical applications, especially in humid environments and rainy days, which can easily cause safety hazards.

[0031] During rainy weather, rainwater can directly splash into the metering box through the ventilation holes. Even on non-rainy days, if the outside air humidity is high, moisture can also seep into the box through the ventilation holes, failing to provide effective protection. The electricity meter, wiring terminals, and other components inside the metering box are precision electrical components with extremely high requirements for insulation. Moisture or rainwater intrusion can damage the insulation performance of these components, easily causing short circuits in the internal wiring. This can not only lead to metering device malfunctions and shutdowns, and distorted metering data, but may also burn out components and even cause serious safety accidents such as fires, threatening the safe operation of the power distribution network and the safety of the surrounding environment.

[0032] Based on this, in order to improve the technical problems of metering devices generating heat during operation in related technologies, existing metering boxes mostly dissipate heat through ventilation holes. However, in humid environments or rainy days, rainwater can easily splash in and water vapor can easily penetrate, damaging the insulation of electrical components after entering the box, which can easily cause short circuits, leading to metering failures, component damage, and affecting operational safety and metering accuracy. The embodiments of this application provide the following solutions.

[0033] Please refer to the following: Figures 1 to 4 This application provides an outdoor waterproof electricity metering box. The outdoor waterproof electricity metering box includes a box body 1 and a box door 5 installed on the box body 1. The side wall of the box body 1 is provided with an array of first heat dissipation holes 11 near the lower end. The box body 1 is provided with partitions 2 at both ends to isolate electrical components. The partitions 2 are provided with an array of second heat dissipation holes 21 near the upper end to prevent rainwater from splashing into the components through the first heat dissipation holes 11 and damaging them. A baffle assembly 3 is provided on the outer wall of the housing 1 at the position corresponding to the first heat dissipation hole 11. The baffle assembly 3 includes a fixing frame 31 and a lifting plate 32 that is telescopically installed in the fixing frame 31, which can reduce the exposed area of ​​the first heat dissipation hole 11 and reduce the intrusion of water mist.

[0034] The outdoor waterproof power metering box provided in this application embodiment forms a multi-layer waterproof and heat dissipation collaborative system through the overall structural design of low-position heat dissipation holes, partition 2 for isolation, and adjustable baffles: the first heat dissipation hole 11 and the second heat dissipation hole 21 work together to construct a directional convection heat dissipation channel, ensuring heat dissipation requirements while using partition 2 to form a rainwater barrier; the baffle assembly 3 specifically strengthens the waterproof protection of the first heat dissipation hole 11, preventing rainwater from splashing in and water mist from intruding. The various structures work together to solve the core problem of easy water ingress in existing exhaust vent heat dissipation, while ensuring heat dissipation efficiency and achieving a precise balance between heat dissipation function and waterproof protection.

[0035] In this embodiment, the box body 1 and the partition 2 are welded together to prevent rainwater from leaking through the connection between the partition 2 and the box body 1.

[0036] With this configuration, the welded enclosure 1 and partition 2 form a stable synergy between the isolation function of partition 2 and the waterproof structure of enclosure 1: it not only ensures the physical isolation of electrical components by partition 2, but also avoids the connection point from becoming a weak point in waterproofing. In conjunction with the first heat dissipation hole 11, baffle assembly 3 and other structures, a leak-free multi-layer waterproof system is constructed, further enhancing the overall synergistic effect of waterproofing and heat dissipation.

[0037] In this embodiment, the second heat dissipation hole 21 partially overlaps with the first heat dissipation hole 11.

[0038] With this configuration, the height difference design works in synergy with the isolation function of the partition 2, the low-position layout of the first heat dissipation hole 11, and the protective function of the baffle assembly 3: it ensures the efficient operation of the multi-layer heat dissipation system through the convection channel, while further blocking the intrusion path of rainwater and water vapor, making up for the shortcomings of the single structure protection, and making the overall waterproof heat dissipation structure form a complementary and synergistic protection system.

[0039] In this embodiment, the cavity between the partition 2 and the side wall of the box 1 is an isolation cavity 12. An inclined plate 13 is provided on the bottom of the isolation cavity 12. A drainage hole 14 is provided on the rear wall of the box 1 at the lower end of the inclined plate 13 to facilitate the drainage of rainwater splashed in from the first heat dissipation hole 11.

[0040] With this configuration, the combined structure of the isolation chamber 12, the inclined plate 13, and the drainage hole 14 works in synergy with the low-position layout of the first heat dissipation hole 11, the protection of the baffle assembly 3, and the welding and sealing of the partition 2. This not only compensates for the potential for minor rainwater leakage in a single protective structure, but also improves the waterproof closed loop through directional drainage, upgrading the overall waterproof system from passive barrier to barrier and active drainage, further enhancing the balance between heat dissipation and waterproofing, and improving structural reliability.

[0041] In this embodiment, a guide groove 311 is provided in the fixed frame 31, and the lifting plate 32 moves up and down through the guide groove 311. A spring pin 321 is provided on the side wall of the lifting plate 32. Multiple limiting grooves 312 are arrayed in the guide groove 311 on the fixed frame 31 at the position corresponding to the spring pin 321, so as to facilitate the fixed limiting of the lifting plate 32.

[0042] With this configuration, the guide groove 311, spring pin 321, and limit groove 312 adjustment and limiting structure make the extension and retraction adjustment function of the baffle assembly 3 stable and reliable. In conjunction with the first heat dissipation hole 11, the isolation cavity 12 drainage structure, etc., the area of ​​the heat dissipation hole can be precisely reduced to enhance waterproofing in humid or rainy weather, and fully expanded to ensure heat dissipation in dry weather. This gives the overall waterproof heat dissipation system dynamic adaptability, makes up for the shortcomings of fixed heat dissipation holes that cannot take into account different environments, and further improves the environmental adaptability and operational stability of the overall structure.

[0043] In this embodiment, a triangular handrail 322 is also provided on the lifting plate 32 to facilitate the user to lift the lifting plate 32. A water-blocking strip 323 is also provided on the top of the lifting plate 32 to abut against the side wall of the box 1.

[0044] With this configuration, the triangular armrest 322 works in conjunction with the spring pin 321 and the limiting groove 312 to make the adjustment of the lifting plate 32 more convenient and precise, ensuring that the baffle assembly 3 can quickly switch to different environments. The water-blocking strip 323 works in conjunction with the baffle assembly 3, the isolation chamber 12, the drainage hole 14 and other structures to fill the sealing gap between the lifting plate 32 and the box 1, and to complete the waterproof closed loop of blocking, guiding and draining, while not affecting the ventilation and heat dissipation function of the first heat dissipation hole 11, further improving the waterproof reliability and ease of use of the overall structure.

[0045] In this embodiment, the box body 1 is also provided with an inclined rain shield 4.

[0046] With this configuration, the rain shield 4, the low-position layout of the first heat dissipation hole 11, the baffle assembly 3, and the drainage structure of the isolation chamber 12 form a multi-layered collaborative protection: the rain shield 4 blocks rainwater in front, and together with the subsequent blocking, diversion and drainage system, it further blocks the rainwater intrusion path, improves the waterproof closed loop, and does not affect the convection heat dissipation inside the box, thus improving the environmental adaptability of the overall structure.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
